* `content` – Ein `str` oder `bytes`.
* `status_code` – Ein `int`-HTTP-Statuscode.
* `headers` – Ein `dict` von Strings.
* `media_type` – Ein `str`, der den Medientyp angibt. Z. B. `"text/html"`.

FastAPI (eigentlich Starlette) fügt automatisch einen Content-Length-Header ein. Außerdem wird es einen Content-Type-Header einfügen, der auf dem media_type basiert, und für Texttypen einen Zeichensatz (charset) anfügen.

* `response`를 반환하기 전에 추가로 `response`를 수정할 수 있습니다.

## 什么是容器

容器（主要是 Linux 容器）是一种非常**轻量级**的打包应用程序的方式，其包括所有依赖项和必要的文件，同时它们可以和同一系统中的其他容器（或者其他应用程序/组件）相互隔离。
